Abstract
A device for feeding precious alloy into a converter belongs to the technical field of metallurgical equipment, and solves the problems that the recovery rate is impacted by a difficult-to-grasp precious alloy feeding method. The device is welded between the outer side of a fire barrier of the converter and the cylinder of an alloy chute. During the alloying process of a precious alloy, the alloy with a weighed quantity is placed in a hopper body and is fed into a steel ladle during the intermediate stage along with the feeding of other alloys, so as to solve the problem that the recovery rate is impacted due to the fact that the precious alloy is fed too early or too late. Therefore, the alloy recovery rate can be improved correspondingly; accidents such as chute jamming and the like caused when bags with the alloy are fed into the steel ladle along with the alloy chute can be avoided; and the stability of the alloying process is improved.
Description
One: technical field
The utility model belongs to technical field of metallurgical equipment, is the valuable material alloying device of a kind of converter specifically.
Two: background technology
In the convertor deacidification alloying process, valuable alloys such as ferro-niobium, vanadium nitrogen all are to become bag in putting the steel process, to add with alloys such as silicomanganese, but receive the influence of the reinforced opportunity and the mode of adding, and the recovery of alloy is generally on the low side.
Secondly, the easy calin chute of packed alloy influence the stable smooth operation of alloying effect and production, if alloys such as valuable alloy unpacking and silicomanganese are placed on the adding of alloy bucket, causes alloy oxidation easily, has reduced the yield of alloy.
Three: summary of the invention
Add the bad assurance problem of mode to above-mentioned existing valuable alloy, the utility model provides a kind of converter valuable material alloying device, and this feeding device can add noble metal separately, has to add advantage convenient, that the alloy oxidation degree is high, the alloy rate of utilization is high.
For achieving the above object, the technical scheme that the utility model adopted is following:
The valuable material alloying device of a kind of converter, described valuable material alloying device is between the converter firebreak outside and alloy chute cylinder.
Above-mentioned feeding device also comprises the hopper body, and the opening direction of hopper body is towards the ladle direction; Described feeding device hinged securement, make feeding device can only towards/away from ladle in cavity direction rotation.
Above-mentioned feeding device also comprises handle, said handle be positioned at feeding device away from ladle end one side; Described feeding device also comprises first supporting leg and second supporting leg that is positioned at hopper body bottom; Said pin joint is positioned at the second supporting leg place.
The beneficial effect of the utility model shows:
This feeding device is arranged between the converter firebreak outside and the alloy chute cylinder, can add precious metal separately, does not remerge interpolation, does not receive the influence of alloy chute.
Valuable alloy is in alloying process; Load weighted alloy is placed in the hopper body,, the intrinsic valuable alloy of hopper is added ladle in mid-term along with the adding of other alloy; Avoided valuable alloy to add too early, crossed the late problem that influences its recovery, alloy recovery can corresponding improve.
Four: description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 plan structure synoptic diagram
Among the figure: 1, handle, 2, first supporting leg, 3, second supporting leg, 4, the hopper body.
Five: embodiment:
Be described in detail with the integrated structure synoptic diagram with to the utility model below:
As shown in Figure 1, the valuable material alloying device of a kind of converter comprises hopper body 4, and the front end of hopper body 4 is provided with opening, and the rear end is provided with bar shaped handle 1, and the bottom is provided with first supporting leg 2 and second supporting leg 3 that is used to support hopper body 4.
The front end hinged securement of said hopper body 4 makes hopper body 4 to be convenient in ladle, add valuable alloy around the cavity direction rotation in ladle of its jointed shaft.For reaching laborsaving and toppling over purpose easily, near the front end of hopper body 4, the utility model is chosen in the hinged turning axle of welding between second supporting leg 3 and the hopper body 4 to described hinged turning axle as far as possible.
In the converter tapping process; When molten steel goes out to 1/4 the time, the alloy worker begins in ladle, to add alloys such as ferrosilicon, silicomanganese, when alloys such as ferrosilicon, silicomanganese add 1/2 left and right sides; Operator lift handle 1, and hopper body 4 rotates with movable axis valuable alloy is added in the ladle.
